Split one file into 2 and renaming the file name

For example of one file:
348657856**56985897568976
N1*PR*Jasmine sdgugu
gughyug
35647856834756
REF*2U*7248
gfhgfdugs
ghdugyuigy4576
4867586
N1*PR*John ~
eghufgguigr
4975876346
REF*2U*SMIL
tfgugrt47587
CAS495787656
5687564

Open in new window


I want to spilt N1*PR*Jasmine to be:

348657856**56985897568976
N1*PR*Jasmine sdgugu
gughyug
35647856834756
REF*2U*7248
gfhgfdugs
ghdugyuigy4576
4867586
CAS495787656
5687564

Open in new window

And
N1*PR*John ~
348657856**56985897568976
N1*PR*John ~
eghufgguigr
4975876346
REF*2U*SMIL
tfgugrt47587
CAS495787656
5687564

Open in new window


However, some files just contain one name, I want them to just leave those files alone?

And for each file that had two, I want the filename like for example if the filename was for the one above :

98475789456.5010.4676897.edi
after splitting them, I want it to show as
98475789456.5010.4676897.edi
98475789456.5010.4676897_copy.edi

$files = './';
$dh  = opendir($files);



$i = 5010;
while(! feof($files)) {
	$contents = stream_get_line($dh,1000,"REF*2U*");
	file_put_contents('new_file.'.$i. $contents);
	
}

Open in new window


I have the code above, but it doesn't seem to work with me.

I'll try to help, but I strongly suggest you consider posting this in E-E Gigs.  It's not really a question with an answer, so much as a requirement for application program development, and for that you will be much better off to work with a professional developer.

This should help you get started.  I do not understand the rules for the file names, but you can write each of the EdiFile objects into its own file using any name that makes sense for your application.

This should also work correctly with a file having only one embedded signal.

Okay, thanks but if there is more than one jasmine, can it keep the file as it is, Like if the name is different thats when it'll split?

Jasmine IkhreishiAuthor Commented:
Also is there a way by using array_splice that I can make the removal of the last two lines dynamically, because some are 5 when some are two (like the example)

Ray PaseurCommented:
There are both short and long answers to both of your recent questions.  Short answers: Yes.

Longer answers: You need to hire a professional application developer to help you write this code.  The process needs to start with a full exposition of the input data and the expected outputs.  You need to create a test data set.  The exercises here are piecemeal and might be steps toward developing a generalized application, but as I wrote above, these are not questions with answers; they are requirements for application development, and they seem to be evolving even as we try to help you answer them.

E-E is pretty good for getting your questions answered, or even getting simple code examples, but we can't develop your applications for free.  Please consider using E-E Gigs.  It will be the fastest path to success because you can hire someone who already has all the knowledge needed to create the applications you need.

If you want to become a developer, and learn all the things a professional already knows, that's a reasonable goal, too.  But you should expect it to take some time, with structured, progressive learning and practice.  Most of us go to college to study these things over several semesters, if not years.  So like most things, there is a trade-off to be made between time and money!

Some good "getting started" resources for new PHP developers are shown in this article.

Best of luck with your project! ~Ray
